Press the bottom button and the cork comes out in about six seconds; press the top one and it lets go. That's the whole job. One charge opens around thirty bottles, and the set has everything else the evening needs: a foil cutter for a neat edge, a pourer that doesn't drip on the tablecloth, and a vacuum stopper that keeps the rest of the bottle for tomorrow. It all stands together on a compact charging base. A nice one to give, too, especially to anyone who finds ordinary corkscrews hard work.
